VARTA Dynamic EFB Batteries

The Dynamic EFB range covers cars with basic start-stop, without energy recovery from braking. It was previously marketed as Dynamic EFB.

Technology

EFB (Enhanced Flooded Battery) is a reinforced liquid electrolyte battery: it incorporates a carbon additive in the negative plate and a polyester separator that holds the active material. The result is approximately double the cycling resistance of a conventional starter battery, at a significantly lower cost than an AGM.

Applications

• Entry-level cars with start-stop
• Vehicles that make many short trips with frequent starts
• Taxis and urban delivery vehicles
• Replacement of the original factory EFB battery

How to choose

If your car came from the factory with EFB, you can install EFB or upgrade to AGM. If it came with AGM, do not downgrade to EFB. In case of doubt, the original battery label indicates the technology alongside the capacity.

Naming and equivalences

Dynamic EFB is the current name of the VARTA Dynamic EFB. Covers cars with basic start-stop, that is, without energy recovery during braking.
